1. 2 tablespoons unsalted butter, divided
2. 2 large sweet onions (such as Vidalia), thinly sliced
3. 1/2 teaspoon kosher salt
4. 2 teaspoons Worcestershire sauce

INSTRUCTIONS

1. Heat 1 tablespoon of the butter in a large skillet over medium until melted. 
2. Add the onions and salt and cook, stirring every 5 to 10 minutes and scraping any browned bits from the bottom of the pan, 
3. until soft and deeply browned, about 40 minutes total. Stir in the Worcestershire sauce, again scraping the bottom of the pan. 
4. Remove the pan from the heat. Meanwhile, arrange a rack in the middle of the oven and heat to 350°F.
5. Melt the remaining tablespoon of butter; set aside.

8. Spread the onions in an even layer over top, then sprinkle evenly with the cheese. 
9. Place the top layer of rolls over the cheese. Brush the top of the rolls with the melted butter. 
10. Sprinkle with the garlic powder and onion powder.
11. Cover the baking sheet with aluminum foil and bake for 15 minutes. 
12. Uncover and bake until the cheese is melted and the rolls are lightly browned, 5 to 7 minutes more.
